On June 4, according to the website of the National Meteorological Center, yesterday, heavy to torrential rain occurred in Guangxi, Guangdong and other places, with localized extremely heavy rain. It is expected that over the next three days, rainfall in Guangxi, Guangdong and other places will continue. Attention should be paid to secondary disasters such as flash floods, geological disasters, and urban and rural waterlogging that may be triggered by localized intense rainfall and sustained rainfall; in particular, Guangxi needs to watch for the disaster risk caused by overlapping rainfall. North China, Northeast China and other regions should watch for the impact of localized severe convective weather on transportation, urban operations, and other aspects.
